Diagnosis of hypothyroidism
Physical examination may also reveal symptoms like:
- Brittle nails
- Coarse facial features
- Pale or dry skin
- Swelling of the arms and legs
- Thin and brittle hair
Laboratory tests that are used to determine hypothyroidism are:
Chest X-ray: A chest x-ray is conducted to reveal an enlarged heart caused by hypothyroidism.
T4 test: T4 or thyroxin is a hormone produced by the thyroid gland. Since hypothyroidism is the condition when the blood lacks the necessary amount of thyroid hormones, a measure of the amount of T4 in the blood reveals whether the person is suffering from hypothyroidism or not.
Serum TSH: Serum TSH is used to measure the amount of TSH in the blood. TSH is a thyroid stimulating hormone produced by the pituitary gland. TSH stimulates the thyroid gland to produce and release hormones thyroxin (T4) and triiodothyronine (T3).
